It's been a while since Japanese boxing fans have had free to air action though over the next few weeks fans will get a number of free to air shows across 4 of the terrestrial channels with each showing at least 1 big name in action.The first of the shows comes a week today as the unbeaten Shinsuke Yamanaka (22-0-2, 16) defends his WBC Bantamweight title against unbeaten Argentinian Diego Ricardo Santillan (23-0, 15) on April 16th. This will be Yamanaka's 8th defense of the title and will see him attempting to continue his reign of terror in the packed Bantamweight division. For fans wanting to watch this one it will be on NTV at 19:56 Tokyo time with the broadcast set to finish at 20:54.For those wanting to watch the undercard bouts for that card they are unfortunately not on a free to air channel.Less than a week later we see action on TBS who will be televising two world title bouts. One of those will see IBF Minimumweight champion Katsunari Takayama (28-7-0-1, 11) defending his belt against Fahlan Sakkreerin Jr (27-3-1, 15) whilst the the other bout will see the mega-popular Kazuto Ioka (16-1, 10) attempt to become a 3-weight world champion as he battles Juan Carlos Reveco (35-1, 19) in a bout for the WBA Flyweight title. The beginning of this broadcast is stated to begin just before 20:00 local time on April 22nd.From what we understand Sho Ishida (18-0, 10) may have highlights shown if the two main bouts both end early.To begin May the televised action continues to roll and Fuji TV will begin the month by televising a couple of interesting looking bouts. The first of those will be Takashi Miura's (28-2-2, 21) WBC Super Featherweight world title defense against former IBF Featherweight champion Bily Dib (39-3, 23) whilst the other will be a bout between Ryota Murata (6-0, 4) and Douglas Damiao Ataide (13-1-1, 6). This show will give Miura a chance to really establish himself with fans whilst also allowing Murata to face a world ranked foe in what should make for an enjoyable card.The hope here is that if both bouts are over early then highlights may be shown from Akira Yaegashi's (20-5, 10) bout, which will see the exciting 32 year old fighting for the first time as a fully blown Super Flyweight.The last of the free to air shows during the little burst of action comes on May 6th when TV Tokyo get in on the action and televise a couple of interesting bouts between Japanese champions and Thai challengers. The first of those bouts will see WBA Light Flyweight champion Ryoichi Taguchi (24-2-1, 8) defending his title against Kwanthai Sithmorseng (49-3-1, 26) in what will be Taguchi's first defense of the title he won this past December. The other bout is a much more mouth watering contest between unbeaten WBA Super Featherweight “super” champion Takashi Uchiyama (22-0-1, 18) and Thai challenger Jomthong Chuwatana (9-0, 4). Uchiyama will be seeking the 10th defense of the title, as he slowly moves towards the Japanese record of 13 world title defenses, whilst Jomthong look to claim a world title in boxing to go along with his numerous titles from Muay Thai.At the moment there hasn't been a time announce for either the Fuji TV or the TV Tokyo show however we suspect details will emerge closer to the date.Of course whilst these channels are free to air in Japan that doesn't mean they will be the only ways to watch the bouts. For example we're aware that the Takayama Vs Fahlan bout will be aired in Thailand, on Mono 29, and the Ioka Vs Reveco bout will be televised in Argentina, on TYC Sports. At the moment however it does seem like some bouts are set to miss out on international coverage and that none of the bouts are set to be televised in the US or UK. Thankfully the free channels from Japan are available via certain methods on line.
